A letter to the editor is presented discussing a mini case series of spectral domain optical coherence tomography (OCT) findings in bilateral diffuse uveal melanocytic proliferation (BDUMP), a rare paraneoplastic disorder.

Background: Lack of clinical tests to quantify spatial components of distortion in patients with full thickness macular holes (FTMH) and epiretinal membranes (ERM). Aim: To develop a test for subjective evaluation of visual distortion in the central visual field around fixation in patients with unilateral FTMH or ERM. Settings and Design: Prospective case-control study carried out at tertiary referral center. Materials and Methods: Twenty-five patients with unilateral macular disease (13 macular epiretinal membranes, 12 full-thickness macular holes), and nine controls (without ocular pathology) underwent ophthalmological examination with logMAR ETDRS visual acuity, near vision and contrast sensitivity assessed. Macular optical coherence tomography and metamorphopsia assessment using Morphision test was also carried out. This test consists of a set of modified Amsler charts for detection, identification, and subjective quantification of visual distortion in the central visual field around fixation. Morphision test content and construct validity, and reliability (test-retest method) were evaluated. Sixteen patients completed an unstructured survey on test performance and preference. Results: Every patient with unilateral FTMH or ERM identified a particular chart using Morphision test (content validity). None of the normal subjects without symptoms of metamorphopsia identified any distortion (construct validity). Test-retest showed a 100% consistency for frequency and 67% for amplitude. The mean amplitude difference between measurements was 0.02 degrees (SD = 0.038). The coefficient of repeatability was 0.075. There was a correlation between Morphision amplitude score and visual acuity and contrast sensitivity, individually. Conclusions: Morphision test allowed detection and subjective quantification of metamorphopsia in the clinical setting in our patients with unilateral macular epiretinal membranes and full thickness macular holes.

The article focuses on the incidence of macula displacement and distortion symptoms after repair of a rhegmatogenous retinal detachment (RRD). It states that patients undergoing primary RRD repair had a postoperative assessment using optical coherence tomography and fundus autofluorescence with the findings examined for correlations with pre-operative features and symptoms. It mentions that the findings found macula displacement is common after RRD repair.

The article describes the case of an elderly woman diagnosed with interconnected orbital cyst and chorioretinal coloboma. The ophthalmic history of the patient includes retinal detachment in the right eye and cataract extraction. Testing of her visual acuity and anterior segments demonstrated a pale lesion inferotemporal at the left macula. The use of spectral domain optical coherence tomography (OCT) imaging for deeper visualization of her condition is also reported.
